I think the place is very good for big group without people with walking issues as the walk to the mrt station is around 10mins. There is a shuttle bus but the timing is until 9pm which will be a problem if you come back after that. Having said that, grab is easy and won’t cost more than 150baht.
The place is clean with the necessary toiletries. Will suggest to get some necessities from 7-11 or the villa market if you have special requirements.
If you intend to leave your luggages after check out, there is a storage right outside the mrt station. Hence, will suggest to time your checkout timing so that you do not need to store your luggages, else book a van and store the luggages in the van.
Otherwise, I think the place and Rebecca/Sarah are fantastic!
